Abstract

A data processing device comprises processing module capable of receiving from equipment in a communications network primary data defining events in at least one primary format, and delivering to a management device in the network secondary data defining alarms representing events, in a secondary format. The processing module comprise an interpreter provided with conversion rules, arranged in the form of scripts associated with the various primary event formats, and arranged to convert, using these rules, primary data received in one of the primary formats into secondary data in the secondary format which can be interpreted by the management device.

wherein said processor comprises an interpreter which is provided with a plurality of conversion rules, arranged in the form of scripts that are interpreted by the interpreter and are associated with a plurality of different primary data formats, and arranged so as to convert, by means of said rules, the primary data received in one of said primary data formats into secondary data in said secondary data format which can be processed by said management device, said interpreter further arranged to deduce alarm parameters from certain primary data received, so as to deliver a parameterized alarm to said management device,

wherein, when the alarm state of the item of equipment in the network is unknown, said interpreter is arranged to extract from said item of equipment chosen information able to allow determination of said alarm state, and then to simulate the sending of primary data representing said state information, so as to generate an alarm intended to indicate to the management device the alarm of said item of equipment, and

wherein each of the plurality of different primary data formats corresponds to a particular script.

2. The device as claimed in claim 1, wherein said interpreter is arranged to make said conversions into a secondary configuration file format by means of an interpreted language.

3. The device as claimed in claim 2, wherein said secondary configuration file format is XML.

4. The device as claimed in claim 2, wherein said interpreted language is selected from a group consisting of JavaScript, Visual Basic, TCL, Perl and Python.

5. The device as claimed in claim 1, wherein, when there are primary data associated respectively with event identifiers, said interpreter is arranged to store at least some of said rules in correspondence with known event identifiers.

6. The device as claimed in claim 5, wherein said interpreter is arranged to store at least one conversion rule defining a default script intended for the primary data associated with an unknown event identifier.

7. The device as claimed in claim 1, wherein said interpreter is arranged to deliver to said management device alarms parameterized by hard coded values.

8. The device as claimed in claim 1, wherein said interpreter is arranged to deliver to said management device alarms parameterized by values extracted from said primary data.

9. The device as claimed in claim 1, wherein said interpreter is arranged to deliver to said management device alarms parameterized by values extracted from the equipment from which it has received the primary data.

10. The device as claimed in claim 1, wherein said interpreter is arranged to extract said chosen information from a management information base of the equipment concerned.

11. The device as claimed in claim 1, wherein said primary data are received in primary formats of the SNMP type.

26. The device as claimed in claim 1, wherein said information resides in a management information base of said equipment concerned.

27. The device claimed in claim 1, wherein the alarm state of said equipment is synchronized or resynchronized using said extracted chosen information.

12. A network management device, comprising a processor which receives, from an item of equipment in a communications network, primary data defining events in at least one primary data format and delivering to a management device in said network secondary data defining alarms representing said events, in a secondary data format,

wherein said processor comprises an interpreter provided with a plurality of conversion rules, arranged in the form of scripts associated with a plurality of different primary data formats, and arranged so as to convert, by means of said rules, primary data received in one of said primary data formats into secondary data in said secondary data format which can be interpreted by said processor, said interpreter further arranged to deduce alarm parameters from certain primary data received, so as to deliver a parameterized alarm to said management device,

wherein, when the alarm state of the item of equipment in the network is unknown, said interpreter is arranged to extract from said item of equipment chosen information able to allow determination of said alarm state, and then to simulate the sending of primary data representing said state information, so as to generate an alarm intended to indicate to the management device the alarm of the item of equipment, and

wherein each of the plurality of different primary event formats corresponds to a particular script.

13. A data processing method in which, on reception of primary data transmitted by an equipment in a communications network and defining events in at least one primary format, there are delivered to a management device of the network secondary data defining alarms representing said events, in a secondary format,

wherein said method further comprising the step of converting, by means of one of a plurality of conversion rules, arranged in the form of scripts associated with a plurality of different primary event formats, primary data received in one of said primary formats into secondary data in said secondary format which can be interpreted by said management device,

wherein alarm parameters are deduced from certain primary data received, so as to deliver a parameterized alarm to said management device,

wherein, when the alarm state of an item of an equipment in the network is unknown, there is extracted from said equipment chosen information able to allow determination of said alarm state, and then the sending of primary data representing said state information is simulated so as to generate an alarm intended to indicate to the management device the alarm state of said equipment, and

wherein each of the plurality of different primary event formats corresponds to a particular script.

14. The method as claimed in claim 13, wherein conversion step is carried out into a secondary configuration file format by means of an interpreted language.

15. The method as claimed in claim 14, wherein said secondary configuration file format is XML.

16. The method as claimed in claim 14, wherein said interpreted language is selected from a group consisting of JavaScript, VisualBasic, TCL, Perl and Python.

17. The method as claimed in claim 13, wherein, when there are primary data associated respectively with event identifiers, at least some of said conversion rules are associated with known event identifiers.

18. The method as claimed in claim 17, wherein at least one of said conversion rules defines a default script intended for primary data associated with an unknown event identifier.

19. The method as claimed in claim 13, in which alarms parameterized by hard coded values are delivered to said management device.

20. The method as claimed in claim 13, wherein alarms parameterized by values extracted from said primary data are delivered to said management device.

21. The method as claimed in claim 13, wherein there are delivered to said management device alarms parameterized by values extracted from the equipment from which it received primary data.
